Ordered too late: Long-lead items get remembered when the stage that needs them is already close.
Suppliers in the dark: Suppliers learn about programme changes after the delivery date has already passed.
Deliveries miss the work: Arrivals don't line up with the trade sequence, so materials wait, or work does.
The programme drives the purchasing.
Supplier quotes compared per trade package inside the live system. The interface is the real one; supplier names and amounts are de-identified samples, because pricing is the supplier's information.
Plan from the sequence: Purchase requirements derive from the build programme, grouped into packages with lead times built in.
Track the long-lead items: Anything with a long lead gets a register entry with an order-by date, visible long before it becomes urgent.
Coordinate suppliers: Orders, confirmations, substitutions and delays flow through one thread per supplier, not through memory.
Land the deliveries: Arrivals are matched to the stage, trade and site readiness that needs them, then handed off to accounting.
Purchasing that reads the programme.
Procurement control starts before the order. The system reads the build sequence, identifies long-lead items, tracks supplier confirmations and keeps delivery timing aligned with site readiness.
Programme-driven purchase planning: Requirements grouped into purchase packages, derived from the sequence.
Long-lead item register: Lead times and order-by dates, surfaced while there's still time to act.
Supplier confirmations: Every order confirmed, every change acknowledged, in one place.
Substitution and delay handling: When an item slips or changes, the impact on stages is visible immediately.
Delivery-to-stage matching: Arrivals timed to the stage and site that can actually receive them.
PO handoff to accounting: The operational side coordinates; your financial systems keep the paperwork.
Part of a working supply chain.
DDDI Group's operations span development, construction and supply. This coordination discipline is built from how those businesses actually buy: sequence-driven purchasing that keeps live sites stocked.
Purchase orders keep landing in your accounting system. This layer coordinates the timing, not the paperwork.
What the system reads: Demand as the programme defines it, not as urgency arrives. (The build programme; Purchase requirements by stage; Supplier confirmations; Lead times and delivery windows)
What it gives back: Purchasing that follows the build, not the panic. (Programme-driven order schedules; Long-lead and mismatch flags; Delivery coordination views; Supplier follow-up drafts)
Common questions.
Does it replace our accounting or ERP purchasing?
No. It coordinates the operational side and can integrate with your financial systems for the paperwork.
Can suppliers see their part?
Supplier-facing views are scoped per engagement, from simple confirmations to shared schedules.
How does it connect to scheduling?
Purchase plans derive from the same build sequence the scheduling system manages.
Procurement risk belongs in the programme, not in the inbox.
